Toshiba have been very successful in merging their mobile phone releases with that of Fujitsu, who they have released a number of smartphones with in the Japanese and their domestic markets. These handsets have used the Android OS predominantly and have plans to develop more compact, highly functional handsets in the future as well. It's unlikely that we'll see these handsets outside of Asia, but for use on worldwide networks, you can get the Toshiba handset unlocked and connect where and when you wish.
